Johnson Controls VG1245ADH923GGA 1/2" Two-Way Ball Valve with Thermal Barrier and VA9203 Electric Actuator

The Johnson Controls VG1245ADH923GGA is a factory-assembled valve and actuator combination featuring a 1/2-inch two-way stainless steel trim NPT ball valve (Model VG1245AD) paired with a VA9203-GGA-2Z proportional spring-return electric actuator equipped with an M9000-561 thermal barrier. This complete assembly is designed for precise control of hot water, chilled water, or 50% glycol solutions in commercial HVAC systems.

Valve Features:

• 1/2-inch NPT threaded end connections for easy installation
• 1.2 Cv flow coefficient for accurate flow control
• Stainless steel ball and stem assembly resists corrosion
• 200 psig closeoff pressure rating
• Forged brass body construction with 580 psig static pressure rating
• Equal percentage flow characteristic with characterizing disk
• Fluid temperature range: -4°F to 212°F (-20°C to 100°C)

Actuator Specifications:

• VA9203-GGA-2Z proportional spring-return electric actuator
• 27 lb-in torque output for reliable valve operation
• 24 VAC/DC power supply with universal voltage compatibility
• Proportional control: 0-10 VDC, 2-10 VDC, or 4-20 mA input signals
• Spring-return failsafe operation (normally open configuration)
• 120-inch plenum-rated cable included
• M9000-561 thermal barrier pre-installed for high-temperature applications

Applications:

Ideal for terminal units, fan coils, unit ventilators, and other HVAC equipment requiring precise modulating control of water flow. The thermal barrier allows operation with fluid temperatures up to 212°F, making this assembly suitable for demanding heating applications. The spring-return actuator provides fail-safe positioning, returning the valve to the open position upon power loss.

Installation Notes:

Factory-assembled and tested for immediate installation. Accepts standard 1/2-inch threaded electrician's fittings for conduit connections. Compatible with building automation systems using industry-standard analog control signals. The valve features maintenance-free design with graphite-reinforced PTFE seats rated for over 200,000 full stroke cycles.
